BUNDLING-PRESS.

Specification of Letters Patent.

Patented June 10, 1919.

Application filed August 2, 1916. Serial No. 112,729.

To all whom it may concern:

Be it known that I, HERMANN ABELE, a citizen of Germany, residing atZurich, Canton Zurich, Switzerland, have invented a new and usefulBundling-Press, of which the following is a specification.

This invention relates to a bundling press which is characterized byhaving an operating footlever articulated to a toothed. rack which bymeans of a coupling is connected. with a movable plate rigidly attachedto rods capped with compressing trays which move toward stationarycompressing trays fixed to socket-tubes on the top-plate of the pressarranged in such a manner that the material compressed between saidmovable and the stationary trays can easily be tied crosswise.

The invention is shown in the accompanying drawings to which referencewill be had hereinafter and in which:

Figure 1 is a section on the line AB of Fig. 3; Fig. 2, a plan showingthe position and arrangement of the compressing rods and trays whichlatter provide rear and side cheeks for safeguarding a bundle forcompressing and allowing same to be tied crosswise; Fig. 3, a top-viewwith the upper plate of the press removed; Fig. 4:, a section on theline C-D of Fig. 1 showing the connecting table with coupling mechanism;Fig. 5, a section on the line EF of Fig. 1. Figs. 6 and 7, being detailshereinafter referred to. Fig. 6 is a top view of Fig. 6, and Fig. 7 is aface view of Fig. 7

The top plate 1 carries four socket-tubes 2 which carry compressingtrays 3 for supporting the bundles to be compressed and tied, and whichtrays form guides for vertically moving compressing rods 1. The rods 4:carry capping trays 5 corresponding to the trays 3 in form and position,see ig. 2.

The lower ends of the rods 4 are fixed in a connecting table 6 throughwhich passes a vertically movable twin toothed rack 7 which has itsupper end articulated to the footlever 8, while the upper end of therack is guided by two pins 9 an a For compressing a bundle, draws therack 7 downward, the latter drawing the rods 4 down when the connectingtable 6 is coupled with the rack by means of two slotted slides 10 whichcan engage in the rack for the purpose and which can be disengagedtherefrom. Two springs 11 urge the footlever 'footlever moves, seeremoving the tied-up and fully compressed the slides 10 toward eachother so as to cause same to enter the teeth of the rack, whileuncoupling is effected by means of a pair of balance levers 12 and 12fulcrumed on the table 6 and pin-j ointed to links 13 for simultaneousmotion which is imparted by a square spindle 1 1 engaged-in the lever 12and passing through the table 6, see Figs. 1 and 1. The spindle li issuspended in a bearing 15 beneath the top-plate 1 and is there, by meansof links 16, connected to a reversing lever 17. By suitably operatingthe lever 17 and engaging same in a hook or catch 18 the spindle iscaused to turn so as to bring the levers 12 to an approximately parallelposition with the slides 10, whereby they are made to close against andengage in the teeth of the rack 7. Figs. 6 and. 6 show the lever 17 andcatch 18 fitted at the underside of the plate 1. lVhen the lever 17 isreleased from the hook 18, a spring 28 pulls it so as to turn the levers12 and 12 in a manner so as to separate the slides 10 from the rack 7 iFor compressing a bundle, the footlever 8 is depressed so that the rack7 and the table 6, being coupled, are lowered. At the same time thefootlever is look dby a pawl 19 which is pivoted to said lever andengages in a twin toothed guide 20 between which the Figs: 1, 7 and 7*.For

bundle from the press the rod 21, which forms a guide rod for the weight23, is made, by its angular prolongation 22, to disengage the pawl 19 iithe following manner: The rod 21 is turnably mounted between two angulararms 24 and 25, and an angular upper prolongation 22 of said rod isconstrained by a spring 26 to keep in contact with the reversing lever17 and to follow the forward and rearward movements of said lever. Thesemovements are followed by the lower portion 22 of the rod 21, thuseither disengaging the pawl 19 by pressure against the pin 27 (see Figs.7 and 7 or leaving said pawl to the pressure of its spring.

The combined action of the various parts for compressing is as followsIn the idle position of the press, the rack 7 is uncoupled and theweight 23, which is suspended over rollers 31 and 32 by a rope securedto the middle of the table 6, has raised the latter with the compressingrods tween the slides 4; the weight being slightly heavier than the lastnamed parts.

fter a bundle has been introduced between the movable capping trays andthe stationary compressing trays, the rods 4 are lowered by handpressure until the capping trays rest on the bundle, and the lever isthen drawn into the hook 18. By the movement of the lever 17 the tablebecomes coupled to the rack 7 so that, by depressing the footlever 8,the rack 7, table 6 and rods l are lowered. At the movement of the lever17, the prolongations 22 and 22* of the spindle 21 move so that the pawl19 is free to engage in the teeth of the guide 20 and lock the press.

For withdrawing the tied-up bundle, the reversing lever 17 is releasedfrom the'hool; l8 and is then drawn about half-way back by its spring'28 till the levers 12 and 12-", which have a certain amount of play be10, come into contact with the slides. By moving the lever 17, theprolongations 22 and 22 turn around so that the prolongation 22 isbrought in contact with the pin 27 of the pawl. Through the earlycontact of the prolongation 22 with the pawl 19 there occurs a certainspace between the reversing lever 17 and the upper prolonga tion 29f. Assoon as the pressure on the footlever 8 releases thepawl 19, theprolongation 22 completes its turn until it comes against the lever 17and at this moment it causes the lower prolongation 2-2 to so actagainst the pin 27 as to disengage the pawl 19 from the teeth of theguide 20. The footlever 8 is now raised by its springs 33 in consequenceof which the pressure from the rack 7 on the slides 10 is released sothat the spring 28 is able to pull the reversing lever 17 over theremaining half of its path, thereby enabling the actuating parts of theslideslO to completely disengage the latter from the rack 7. At thismoment the weight 23 raises the compressing rods k,

The hand-operations for using the press are shortly as follows:

For compressing, perform a slight lowering of the compressing rods tillthe capping trays 5 rest on the bundle, then pull the reversing leverinto the hook and depress the footlever.

For releasing the tied bundle: disengage the reversing lever by pressureagainst its retaining hook and press on the footlever.
